Google Calendar helps users keep track of all their itineraries and to-do lists everyday. After creating their own calendar, users can set different colors to indicate the properties of the calendar, making it easy to distinguish from company meetings to private activities, thus arranging time conveniently and efficiently. Each calendar and each activity can be set as private or shared. The detailed information under specific activities in the shared calendar can also be hidden, which is a considerate and privacy-protecting small function. Who can see your calendar and what detailed information can be shared are completely up to you to decide. Want to schedule an event? You can directly create invitations, send reminders, and track replies within Google Calendar.
